to run an EA do you have to know how it works first?
yes right, so to run EA well there are a number of sequences that must be done first, except EA is made by yourself or from its own engineering technique and ask to be made to be an EA by a programmer, and even then it must be really precise in making logic so that it can really match the trading techniques that have been run so far and so can produce a consistent profit because basically EA is made to help the trader when he can't run his trading activities
